What makes this episode really good is more extensive participation by Ann Morgan Guilbert as Millie Helper. First Millie gets the paranoia going by giving Laura an alarm concealed in what looks like a fountain pen, then by telling Laura not to take a shower, referencing Hitchcock's Psycho. She only ramps the paranoia up when she returns unexpectedly. The scene where she's just arrived, searching for Laura while carrying on a loud monologue is good, and, especially, the scene where she tries to quiet Laura by holding a pillow over her face.
I always liked Millie and wished she'd played a greater part in the series.
